The american law wouldn't be imposed on the seller. They'd merely have to accept the limitations of their county's law on the buyer, with regard to their inability to prevent resale. Which isn't as much forcing our law on them as not letting them force theirs on us by attaching it to a sale. Anyways, the entire issue is a red herring created by fraudsters. There are already the concepts of renting or licensing which are limited. Sale is unlimited. Anything else is false advertising. To retain resale rights simply don't sell something. If that isn't enough for you (in the generic) you're a criminal.
